Application filed April 9,

'Gothenburg Sweden, have invented new and useful Improvements inCalculating Machines, of which the following is a specification.

The calculating machines as at ,present in use are based, as known, uponthe decimal-system. The circumstance, however, that a great number ofmoney, measure and weight systems are still employed which are basedupon other numbers of relation between the various units than the number10 characteristic to the decimal system, as, for instance, the Britishpound system. causes great difficulties and reduces the employment-ofthe machines for calculations of numbers accordingto said systems.

In well known multiplication machines it is possible by so calledanalogy calculation to perform multiplications of measure,

ioney or other quantities based upon other` systems than the decimalsystem. In such case the result,.however, will always appear as a numberaccording to the decimal system.

The object of this invention is now to provide means whereby the resultas obtained according to the decimal system may automatically betranslated to a corresponding result in another system. To this end thecalculating machine is provided with a gearing device connected to thosemembers of'any of the countersv of the machine vcorresponding to thedecimals, to translate the indications of said decimal members intothose indications of another system correspondingr to the decimalequivalent as indicated by the said first mentioned indi-- cation.

One eX'ample'of the invention as adapted to the British pound systemwill be described nhereinbelow with reference to the drawing. It shouldbe noted, however, that the invention may, of course, be applied to anyother money, measure or weight system as well.

In the drawing, Fig. 1 shows a front elevation of a calculating machineof the Odhner type constructed according to this invention. Fig. 2 showspart of the totalizing counter of such a calculating machine togetherwith a gearing device according to this invention combined with saidcounter. Figs. 3, 4, 5 and 6 show de- 1923. Serial No. 630,938.

Yvelopments of indicating wheels included in said gearing device.

The machine shown as an example is adapted for translating the firstthree decimals of any number, as appearing in the totalizing counter,into the corresponding values in shillings and pence. In the drawing,the numerals 1, 2 and 3 indicate the first three decimal wheels of thetotalizing counter. The first decimal wheel 1 is connected as by atoothed gearing including an intermediate wheel 4 to a figure wheel 5,viz, the shilling wheel, in such a way that one revolution of the wheel1 will likewise cause one revolution of the wheel 5. The graduation ofthe shilling wheel 5 is shown in detail in Fig. 3, which shows adevelopment of the wheel 5. The graduation is arranged in two columns,each of which containing ten figures. The left hand column comprises theeven shilling numbers from 0 to 18 inclusive, while the right handcolumn comprises the odd shilling numbers from 1 to 19 inclusive. Withthis graduation the shilling wheel upon each step of the first decimalwheel 1 (20.1) will move a distance corresponding to two shillings whichis what is desired, inasmuch as O.1:2sh. The graduation of the wheel 5appears through an aperture formed in the front plate of the machine,the height of which corresponds to a figure on the wheel 5 and the widthof which corresponds to the width of the vwheel 5.

Now proceeding with the second decimal wheel 2 it should be observed,that one halfrevolution of said wheel (:0.05) should correspond to lshilling, because 0.05:1sh. The indication of the wheel 2 should thusappear on the shilling wheel 5. To this end the wheel 2 is connected bya toothed gearing, including an intermediate wheel 7 to a wheel 8coaxial with the wheel 5 and provided with a collar 9 concentricallysurrounding the wheel 5. The collar 9', whichY is shown as developed inFig. L1, is formedV with ten apertures placed so that five thereof. asindicated at 11, will be in register with the left hand figure column ofthe wheel 5 and the other five, as indicated at 12. will be in registerwith the right hand column of the wheel 5. Furthermore, the arrangementis such that the apertures 11 are situated on that portion of the ring 9facing the aperture 6, when the decimal Wheel shows 0 4, While theapertures 12 are in register Withthe aperture 6 when the Wheel 2 shows 59.

es regards the third decimal Wheel 3 it should be observed that eachstep thereo :0.001) should correspond to 0.24 penny, as 1532240 pence.The movement of the third decimal Wheel 3 is imparted by means oit atoothed gearing including an intermediate Wheel 13, to a penny Wheel 14rotatably mounted on an extension ot the shaft ot the Shilling Wheel.ofthe penny Wheel 14, `which is shown as developed in Fig. 5, isgraduated in multiples of 0.24 penny rounded ott in any suitable Way tofull quarters ot a penny and placed in live columns, each of which con'-taining ten numbers, that is the lirst column Y as seen from the lettcontains the numbers 0 to 2.25 inclusive, the second column con- A tainsthe numbers from 2.50 to 4.50 inclusive and so on, tue last columncontaining Jfrom V9:50 to 11.75 inclusive. appear through an aperture 16formed in the front plate of the machine. Y of this aperture correspondsto a figure on Wheel' 14, vvhile the rividth of the aperture 16corresponds to lthe entire Width et Wheel 14. Y l

Each step of the second decimal Wheel 2 -0.01) vshould correspond to 2.4pence. To this end there is att-ached to the shaft l0 Wheel 15 having acollar 17 concentrically surrounding the Wheel 14 which is driven by thedecimal Wheel 2 through theJ intermedium of the which is keyed to theshaft 10. Said collar 17, which is shown as developed in F 6, is formedwith ten apertures placed in such a Way that with the second decimalWheel 2 set on 0 and 5 the first column `gu-res of the penny Wheel 14Will` appear' through the aperture 16 of the cm'erplate` .vh'i'l'e withWheel 2 set on1 and 6 the second 'Y column figures Will Vappear throughaperture 16 and so on. With this construction Aea'chstep of the second'decimal Wheel 2 will change the indication o't the penny Wheel 14 by2.4 penny, the difterence between tivo adjacent figures amounting to10X`0.24 pence, that is 2.4 pence.

ln order to still further illustrate the invention a definitecalculation example, will be Y briefly described'V -he're'i'nbelow ymoves one step or two shillings. The cylindrical surfaceV The numbersshould The height gears 7, 8, `the latter of Let it be assumed that acalculating operation in pounds should be petormed in :the machine Vandthat the result orf this opera'- tion should he 0.62696 in thetotalizing counter. Vln this case itis of no import-ance for the mat-terof this invent-ion, in what Way theJ calculation is performed, let it beVby analogy calculation or in any difiere-nt Way.

At each step of the Wheel 1 the Wheel 5 After the vheel 1 has moved sixsteps, that is to say from 0 to C 6 the figure row 12, 13 l VWill thusbe in register with aperture 6.

The Wheel 2 is moved Jfrom 0 to 2 Vso that, as Will appear from thestatement hereinbefore, the ligure 12 i of rWheel 5 will appear throughaperture 6,

The Wheel 3 is moved from 0 to 6 i. 1n this movement :the penny Wheel 14moves to lthe position in which the ligure row 14,34, 691;, Sil, 11iwill register With aperture 16. rlihe Wheel 15, 17 cont-rolled Yhy thesecond decimal Wheel 2, has been rotated, however, as a vresult of thesetting of the Wheel 2 on fthe figure 2 into position to register thethird aperture, shown at c in Fig. 6, with aperture 16. The number 64,-will not: appear through said aperture. The result will thus he 12sh64d.

It should be noted that Vthe described translating mechanism may beapp-lied to any counting mechanism of the machine other than thetotalizing counter.
